"Thank you so much for doing this with me Renee! I think this sounds like so much fun!" Lisa Hoskins said as her friend walked up to her.

They were in front of a plain building like any other in every industrial park in America. The sign above it simply said 'Other Side VR Experience'.

"It's definitely going to be interesting, that's for sure haha" Renee Collins replied as the two women embraced in a hug. "And yes, it's going to be an absolute blast seeing the world through your eyes"

"It's going to be a definite eye opener for you. You've heard me tell you stories but now you're going to get to see it all for yourself" Lisa said with a knowing look in her blue eyes and a slight sneer of built up frustration on her lips.

Renee, who had not been able to touch her hands together as she embraced her friend, now gave Lisa a sympathetic smile and nod "I know honey...I know"

"You've always been my friend and encouraged me and held my hand while I've cried so doing this with me just solidifies all that!" Lisa acknowledged. "I know you've never talked bad about me but, I could still always tell that little bit of pity in your voice towards me"

"It's only because I feel so bad and can't do anything real about it!" Renee said.

"Well if it can't be real, at least it can't be virtually real!" Lisa said. "It's the only way I'll get to experience what it’s like to be tall, skinny and pretty!"

Renee could only smile and shrug. She gave Lisa another hug and said "I'll do whatever I can to make this as real as possible"

"I won't want to leave! I won't want to take that headset off haha!" Lisa replied. 

"Then what are we waiting for? Let's go get started!" Renee said opening the door.

The two formed a perfect 10 as they walked side by side to the front desk. Renee, tall and thin as the 1 and Lisa, short and round like a 0.

The two women had met in college as randomly assigned roommates a dozen years earlier. Now at 30, they had taken different career paths but their friendship had on grown. Neither were married but Renee had a boyfriend. 

Lisa was a professional therapist while Renee was an accountant. Their differences were, of course, their looks.

Lisa had very fair blonde hair and pale blue eyes. She stood just 5'2" and weighed well over 300 pounds. 339 to be precise. 

Renee stood 5'9" with dark brown hair and eyes that matched. At just 135 pounds, she had a trim, athletic build with a smaller chest and narrow hips.

"Hello! You must be here for the 10 o'clock appointment" the young man behind the desk said with a smile.

"Yes...Hoskins and Collins" Lisa said huffing a bit already by coming through the lobby and being outside in the heat. 

Renee could see a bit of sweat dampening the back of her friends' blue tank top.

"My name is Tom and I'll be guiding you through today's session" he said pulling out two clipboards and a lot of paperwork. "Once you fill these all out, bring them back up and we'll get you all fitted out and started"

The two women took a seat and began filling out all kinds of sheets. A lot of legal disclosure forms, liability waivers, and other stuff.

Renee saw one stating 'Special Exclusive Free upgrade' and she checked the box thinking "hey...why not" as boredom set in.

She looked over at Lisa as she concentrated on her forms. Lisa's ankles were crossed and her legs pressed together all the way up.

Sausage toes, puffy feet, cankles, thick bulging calves, fat thighs, wide hips and a huge soft ass. An overhanging belly, large pendulous breasts, full and fat upper arms, a thick neck and a double chin. "This is definitely going to be interesting" she allowed herself to think.

Renee went back to her forms, crossing her legs at the knee and bouncing her left foot as she tossed her hair back off her face. Lisa looked up "if only this was more than just virtual reality…" she thought.

Lisa's cheeks burned and flushed. She could never admit how many times she had switched bodies with Renee in her imagination and dreams. Ever since they had first met, she had wished that the two of them would somehow, someway, against all odds and possibilities, swap bodies. 

Whenever she felt down and low, she would put herself in Renee's shoes. She daydreamed what it would be like to be her and, vice versa, to have Renee be her. 

She would picture the look of shock on Renee's face as the pounds piled onto her and the surprise as she watched Lisa slim down. She visualized their faces changing, their features morphing. Their bodies changing down to the smallest details.

Renee was stronger than her; she always pictured her being able to withstand the looks and whispered comments better than she ever had.  And in those times she couldn't,  her skinny friend Lisa was right there to pick her up. "At least I get a visual to my fantasy now" she reminded herself and she tingled all over. "I guess it'll have to do"

The form piles ended with a waiver that was more than 15 pages long. Both women just signed it and looked up. 

"Ready?" Renee asked standing up. She grabbed Lisa's clipboard and stack of papers and carried them both up as Lisa stood and waited.

"Follow me back please" Tom said with a smile as he opened the door and held it open for both of them.

Renee stepped aside as Lisa waddled in. Tom pulled out equipment and began to adjust them. Programming them, putting in chips and readers, testing cameras and head rigging.

In the end, both women were fitted with a harness vest that carried a 24 hour battery in it along with sensory receptacles. They would also wear a camera just by their eye to record everything they saw, did, said, or heard. After a week of wearing these, they would return them. The footage would be edited and processed into a program that would place them into each others life to experience it like they had never thought possible.

Both got a few looks and comments about their getup in the beginning but after a bit, they were ignored. VR setups like these were becoming more popular and therefore, more accepted. They both settled into a normal week. 

When they met for lunch halfway through Lisa said "Now this is going to be trippy when we play this out. Am I me or am I you haha?"

"I can’t wait to see this. I'm finding myself more and more curious to go through the final product" Renee admitted "This is going to be so fascinating"

Renee ate her meal and as they chatted, it really hit her that she would finally really get an inside look at Lisa's life.

"What if I really were Lisa?" She thought.

From time to time she pictured what it would be like if their lives were actually reversed. She would picture the look of shock and awe on Lisa's face as she slimmed down and surpassed her in height. She would jump up and down as her hair darkened and their faces changed. But she would always have a look of pity in her eyes as she looked down at her. Renee would be the fat one. She pictured herself patting down, checking out her wide body and as Renee looked up, Lisa would be looking down.

"Even if we were to only be able to swap our heights" Renee thought "That would at least help her out a little bit" 

"I'll see you on Saturday morning" Lisa said as they were leaving.

"Yep...10 o'clock" Renee confirmed with a nod. 

On Saturday morning, Tom was waiting for them. They turned in their equipment and waited.

During the next two weeks, they talked about what was coming Non-stop but neither would give any details but both were already projecting themselves into the other one's reality.

The big day arrived and it was time.

Lisa arrived first and was waiting in the lobby wearing a light green loose top and tan shorts.

She laughed seeing that Renee also had on tan shorts but her top was a light green tank style top that was form fitting.

"Twinsies!" Renee called out.

"How appropriate!" Lisa added.

"Great minds think alike" Renee said as Tom moved to the door.

"Good Morning ladies I'm sure you're excited to get going! This is a big day for both of you...life changing haha. I can guarantee you will never look at the world the same way again" he led them down the hall past where they had been originally to a larger room with two doors off to each side.

"When you first load in, you two will interact with each other in real time. You're not going to believe your eyes as you start out, it is mind blowing!" Tom assured them. "Once you adjust, you'll head off into one of the side rooms and the program will begin and you two will recreate the week as each other. Once that is done, it's back to this main room where you will once again get to interact with each other in real time before we wrap everything up okay"

"Sounds good to me" Lisa said.

"Yeah...me too" Renee nodded.

"Then let's begin" Tom said. They were back in their harnesses but this time the VR headsets went on instead of the cameras. Wires were connected and the room opened up to them. Tom slipped out just as the headsets booted up.

Renee knew she was wearing a blocky headset as was Lisa but when she looked over and around, she saw Lisa clearly, without any extra gear.

"Renee...I can see you" she said putting her hand out.

Renee took it and the clasped hands. "I see you too but nothing has changed. In fact I can’t see your mask or harness so we must be already going you know"

"This must be our adjustment period" Lisa said.

"Must be…" Renee said. As she looked at her friend and held her hands, everything started to change. She was standing still but felt herself shrinking. "What the heck?!"

Lisa's jaw dropped as her perspective changed. She felt like she was growing taller and in her sight, she was rising up against Renee. They came even and then, she surpassed her friend in height. "Oh my Gosh this is so amazing! It's like we're actually switching places!"

"I know Lise! I can feel it! You actually look taller than me! It's like you're growing and I'm shrinking!"

"This is honestly my wildest dream come true! You have no idea how...Ope! Renee! You!" Lisa broke their grasp pointing "You’re getting fatter! I can see your legs getting bigger! And...and your stomach too!"

Renee looked at herself and indeed saw her body spreading out. Her belly was pushing out but she could also see her thighs spreading wider. Her breasts now grew larger and swung down. She turned and lifted her arm in time to watch it expanded to double its size with fat. 

"Oh...my...God. It looks so real!" Renee said.

"I know right! This is amazing...astounding!" Lisa said. She looked down and saw her feet. Long skinny painted toes wiggled up at her. Long thin tan legs...no belly or boobs to obstruct her view. Everything flat, trim and toned. Out of her peripheral vision, she saw long, dark brown hair hanging, dangling down and she jerked back and up. She saw Renee staring at her.

Renee, fat and short, staring back at her with a look of shocked curiosity on her face.

Lisa watched as Renee's hair turned blonde and her cheeks inflated. Her eyes narrowed, jowls and a double chin formed.

Renee stared at the tall brunette in front of her as Lisa's facial features tightened and defined, taking on her look, her face. It was like looking in a mirror but yet, not.

"Wow" was all Lisa said.

She looked down, the ahead, then down again, then ahead again as a warm smile spread across her face.

"Oh my God" Renee said again doing the same up and down ballet. 

They moved closer to one another, examining the other in awe. Renee reached out and touched Lisa's stomach. "I read about this. I was reading an article about using VR to bodyswap and it only takes a few seconds for your mind to adjust to being the other person. Your stomach feels firm to me"

Lisa looked down and saw the chubby hand touching her. She knew she still had to have her gut but to her, she couldn't see it. She saw another hand come into view. Long thin fingers wiggled and she too felt a strong flat stomach there "This is absolutely fascinating"

Lisa now reached out and could swear she felt nothing but soft fat as her fingers touched Renee's stomach.

Renee put her hands to her hips and could feel them press into soft flesh. She leaned way out to have to see her feet. "I'm adjusting to this….I...whoa"

The wall in front of them now turned into a floor to ceiling mirror and they got a new view of themselves and each other in full comparison.

Lisa laughed and pointed and Renee turned to her "That laugh" she said.

Lisa turned hearing Renee speak and their shock returned.

"You sound different!" Lisa said.

"So do you!" Renee said in return.  "Did they make our voices change too?"

"Well they recorded us so probably...is that how I sound? I don't sound like that and hey you know what? Even the voice inside my head sounds different. This must be what you sound like to yourself! Man this is so trippy!"

"It's so complete" Renee was saying as the mirror shut down and the side doors opened. 

"I guess this is where we go our own way and start our week" Renee said.

"See you in a week" Lisa added.

Renee thought she was walking strangely as she headed to her door. It felt like she was waddling.

Their worlds had been recreated in the program and in miniature in their rooms. Chairs, desks, beds were placed around for them to use and adjust to. Meals had been recreated so they would eat whenever the program said they should. Full bathrooms had been set up for use.

Walking would be mostly in place but a treadmill could recreate longer journeys. 

Clothes had been placed in the rooms so they could change. They would truly spend a week living the other's life.

Lisa was ecstatic. She felt great as endorphins told her that was actually was skinny Renee. She found herself driving home after the initial appointment and going on errands. She ended up going out to dinner with her boyfriend and then, enjoying some extracurricular activities with him. 

Seeing her strong, long, trim legs up in the air as she could sense him inside of her. "This is great!" She thought as she could feel their sweaty bodies together. 

Routine activities were exhilarating to her. She walked like Renee now. No waddle or excess weight keeping her down. Guys stared at her but for totally different reasons and she loved it. She ate less, exercised more. She showered Renee's body, brushed Renee's teeth, wore Renee's clothes, worked Renee's job...Lisa was Renee.

Renee was huffing and puffing leaving the office after that initial visit. She squeezed behind the steering wheel to drive. She waddled through her errands resting often. She spent evenings alone watching Lisa's shows. She felt tired and worn out. She lived a sedentary life. Everything took effort. She ate more, moved less. She did everything as Lisa and became acutely aware that it felt like everyone looked at her with either disgust or scorn. She heard the snide and mean comments but couldn't ignore them. She empathized at first but then personalized those comments as she thought more and more of herself as Lisa. She looked down and saw her. She looked in every mirror at Lisa's face and body. She showered Lisa's body, she brushed Lisa's teeth, she wore Lisa's clothes, worked Lisa's job and it felt natural to her. Renee was Lisa.

She ate more and slept more in a sluggish cycle. She found herself at lunch. She realized where she was in the program and she blushed bright red as she saw Renee, beautiful, tall, slender Renee walk in.

"Renee! You look great!" Renee said.

"Awwwww thank you Lisa but it's just me haha. Same old Renee as always" she easily hopped into the booth seat.

Inside their rooms both Lisa and Renee knew this was not how their lunch had started but they seemingly couldn't stop it so they went with it and played along.

Circuits rewrote the scripts and adjusted memory as the meal played out in a different way. Conversations were natural and they flowed easily but both women were now on a different path. The program was learning and adapting. 

After their meals and more chitchat they acknowledged their equipment and where they were in the experiment. 

"I can’t believe I have to wear this harness and camera for another 3 days" Renee said squinting into the sun as she looked up at her tall, thin friend.

"Good thing they're waterproof haha" Lisa replied looking down.

Renee looked closely. She could swear there was pity in Lisa's eyes toward her. 

Standing in her room Renee shivered all over.

Looking down at her friend Lisa couldn't stop the feeling that suddenly washed over her. She felt superior.

"What if…?" Lisa thought.

"What if…?" Renee thought as their eyes met.

The Computers whirled in the main room. Programs adjusted again. The chips inside the headsets, recording and processing at all times went into overdrive.

"What if we swapped for real?" Their thoughts synced up and overlapped. In their heads they could hear both of their voices merge, then separate,then merge again as they internally said "What if this was how we really were? What if we really switched bodies and lives?"

"I'm Lisa!" Renee heard clearly in her head in a loud strong voice: Lisa's voice.

"I'm Renee!" Lisa heard boom inside her mind in Renee's voice.

"This is my body" they both thought and they both looked down at themselves.

"It's mine...no...I…" Renee thought.

"It's mine...yes...I…" Lisa thought.

Everything went into slow motion to both of them.

"Give it back!" Renee thought.

"Give it up!" Lisa thought. 

Somehow they could hear the other's thought. Faint and distant like an echo.

"It's mine...that’s yours now" Lisa thought, concentrating. "We can make this real"

"You and me...me and you" Renee thought, her blood running cold thinking she was losing a struggle of wills somehow. "This isn’t real! This is a VR simulation!" Renee thought. She reached up but all she did in front of Renee was put on a pair of sunglasses.

"I've got to get back to work. I'll see you later Lisa" Lisa said with a smile.

Renee smiled back "Yeah me too! I'll text you later but we will definitely see each other Saturday"

"10 o'clock sharp" Lisa replied now saying the words the real Renee had said as they departed the actual lunch.

Lisa walked away as Renee stood watching for another minute. "What just happened? That wasn't how it happened...was that? That was weird…" she thought as she waddled to her car and back to work. 

Lisa didn't dwell on what had just happened. "I feel different" she realized as she went back to her previously played out program. She shivered all over.

That night, they both contemplated where they were.

Renee lay on her bed feeling worn out and weighed down. Her breasts sloped off to the sides, her belly rose and fell with her breathing. The waistband of her panties dug into her ample flesh and she could so feel the slight friction of her meaty thighs as they moved against each other. She lifted her right leg and rotated her foot and ankle in the air feeling the weight and effort it took. 

She grabbed her phone and texted Lisa. Of course she had to pull up Renee in her contacts "get used to it" rumbled a thought through her head. 

She text out 'Something happened today at lunch. I think the program glitched. There's no possible way I'm texting right now what you texted that night! We're in uncharted water and I think something big has shifted between us'

She waited. The ping of her phone made her jump and seeing 'Renee' come up confirmed it. 'I know. I'm typing something different to you too right now. How can that be? It's like there are gaps now that we control in real time but other things are still going forward via the program. We can't stop'

Lisa sat cross legged on her bed. Something that should be physically impossible. Her phone sat in her lap as she texted back and forth with 'Lisa'

Her heart was pounding along with her head. 'Take a picture of yourself and send it to me'

Lisa stood and snapped a mirror selfie.

'That’s not what I wore to bed that night'  was the reply she got. Lisa stood in a black tank top and panties as she replied 'Well how am I supposed to know that. Grabbing these felt natural'

A picture came up of Renee's fat body in just panties and she quickly typed 'I never sit around like that! I always cover up'

'So did I every other night so far but tonight this felt right'

Renee said heavily on her bed, feeling it sag under her weight. 'Wow' pinged up on her phone from 'Renee'

All she could do was shrug. And worry.

The next two days went by fast, feeling like they were running like they should be going as both were very busy.

Friday night, Lisa got another round with her boyfriend while Renee went to bed early.

They woke up, their week had passed and at 10 o'clock after a simulation drive, their doors opened.

Renee shivered as she stepped cautiously into the main room. She looked down and still saw what she had seen all week. Then she saw Lisa step in sheepishly. 

Tall and thin, she pulled her long brown hair up into a quick top knot as she walked in "Hey" she said as she put up her hand in a shy wave.

Renee found her heart pounding as she replied "Hey" in a very weak and shaky voice. They walked towards the middle and each other, Lisa covering more ground faster.

Renee huffed a bit, breathing heavily "Look at you go" she said coming to a stop and looking up. "You painted your toes a different color" Renee noticed immediately looking up with surprise.

"I had nail polish and well it was so much easier than before you know so…" she trailed off with a shrug and a slight twirl to her left.

"So how does this end? Do we…"

"Please stand by" a voice overhead said making them both jump "Your program is entering its final stage, thank you for your patience. Please keep all equipment on"

"Oh okay" Lisa said rising up on her toes and bouncing effortlessly.

"So you were right. I really did see an entirely different world as you" Renee admitted.

"I did too. I’m not surprised but I am hurt you know. Now that I've seen how you're treated as opposed to how I've been treated my whole life" Lisa said looking down.

"I understand. I get it. I had no idea really how it was going to be. I thought I did, but, I didn't" Renee said. "I really do appreciate and can empathize what you go through now"

"You’re going to hate me but I'm jealous of you. I know you can't control it but your life is so much easier than mine" Lisa said "I just had to say that before this is all over. I'm sorry if that hurt your feelings"

"No, I understand that...I wish it wasn't"

"You have an idea now why for me, this was more than just a quirky little fun thing. I've honestly pictured and imagined that I was you for so long. Whenever I get overwhelmed, I envision exactly this!" Lisa waved her arms around. "I could never admit to you before that living as you was my fantasy I used to keep going. Switching us like this...I always thought you could have handled being me better than me" she blushed and shrugged and turned away. "I'm just so tired of being heavy. I can’t take it so...picturing me as you and you as me…"

After a moment, Renee said "I pictured it too. I wondered what it would be like too. Never as often I'm sure but sometimes I thought about us swapping places too"

"Really?!" Lisa was shocked. 

"Yeah I thought it would be interesting and it would give you a break you know...now I know that was White Knight stuff though. Stupid of me to think I was doing you a favor in those fantasies"

Tears welled up in Lisa's eyes. "If you're telling me the truth, that makes me so happy"

"Oh it’s absolutely true! I swear to God, I have thought and wondered what it would be like if this was really us. Oh! I also thought about what if we could at least swap height! At 5'9"...that would at least help right?"

"So during our lunch…?" Lisa started.

"I don't know what was up with that. I think it created a glitch in the Matrix or…"
